Description

The present invention relates to a value or security product, in particular an identity card, and a method for its production. Such value or security documents can be, for example, a personal document, a check card, a non-personalized authorization ID such as a ticket or a means of payment, or a value or security element intended for product security.

Valuable or security products, in particular value or security documents, serve to verify the identity of a person or thing or a claim, for example for payment of a sum of money or for the surrender of a product or the provision of a service. To this end, it must be ensured that the product cannot be imitated, falsified or adulterated, or only with considerable effort. The product therefore contains security features that are extremely difficult or even practically impossible to replicate. For example, like banknotes, the product is made of a material that is not readily available. Additionally or alternatively, security features can be formed by special colors, for example luminescent or optically variable colors, optical elements such as holograms, tilt images, kinegrams, lens or prism arrays, as well as guilloches, mottled fibers, security threads and others.

Although there are many security features that are used, many counterfeiting of valuable or security products are still successful; especially those in which a portrait attached to the valuable or security product has been subsequently forged or falsified. This is done by painting over the existing portrait finely, partially or completely, with a thin film being pulled on afterwards in order to make the fake - at least largely - invisible to the human eye.

It is therefore the object of the present invention to provide a valuable or security product and a method for its production which take account of the disadvantages mentioned above.

The above objects are achieved with a valuable or security product with the features of claim 1 and a method with the features of claim 6. Advantageous configurations with expedient developments of the invention are specified in the dependent claims.

In particular, the valuable or security product, preferably an identity card, comprises a carrier material and a portrait image attached to it or formed from one or more printed layers. To secure the portrait image, a tactile security feature formed by means of a laser and comprising at least one straight line is applied or incorporated in at least one of the printed layers of the portrait image or in at least one protective layer covering the printed layers.

This configuration makes it possible to introduce a so-called “Level 1” security feature into the portrait or facial image of the valuable or security product or to attach it to it, which can be easily checked by a person without technical aids.

The value or security product can be a value or security document or a security element, i.e. an element that is connected, for example, to an object to be protected against imitation, forgery or forgery, for example a sticker, label or the like. For example, a passport, an identity card, a driver's license or another ID card or an access control card, a vehicle registration document, a vehicle registration document, a visa, a check, other means of payment, in particular a bank note, a check, a bank can be used as a value or security product -, or a credit or cash card, a customer card, a health card, a chip card, a company ID, a proof of eligibility, a membership card or another ID document, whereby it should be ensured that this has a portrait photo or one attached to it is.

The valuable or security product is preferably in ID 1, ID 2, ID 3 or in any other format, for example in booklet form, as in the case of a passport-like object. The valuable or security product is generally a laminate made up of several document layers, which are precisely connected to one another under the influence of heat and under increased pressure. These products should meet the standardized requirements, for example ISO 10373 , ISO / IEC 7810 , ISO 14443 .

The product layers preferably consist of a carrier material that is suitable for lamination. The valuable or security product can, however, preferably be formed from a polymer selected from a group comprising polycarbonate (PC), in particular bisphenol A polycarbonate or a polycarbonate formed with a geminally disubstituted bis (hydroxyphenyl) cycloalkane, polyethylene terephthalate (PET), their derivatives such as glycol-modified PET (PETG), polyethylene naphthalate (PEN), polyvinyl chloride (PVC), polyvinyl butyral (PVB), polymethyl methacrylate (PMMA), polyimide (PI), polyvinyl alcohol (PVA), polystyrene (PS) , Polyvinylphenol (PVP), polypropylene (PP), polyethylene (PE), thermoplastic elastomers (TPE), in particular thermoplastic polyurethane (TPU), acrylonitrile-butadiene-styrene copolymer (ABS) and their derivatives, and / or paper and / or cardboard and / or glass and / or metal and / or ceramic. In addition, the product can also be made from several of these materials. It is preferably made of PC, PVC and PET. The polymers can be either filled or unfilled. In the latter case, they are preferably transparent or translucent. If the polymers are filled, they are opaque. The above information relates both to films to be joined together and to liquid formulations that are applied to a preliminary product, such as a protective or topcoat. The product is preferably made from three to twelve, preferably four to ten films. The foils can also have printed layers. A laminate formed in this way can then be coated on one or both sides with the protective or topcoat or with a film. The film can in particular be a volume hologram, a film with a surface hologram (for example a kinegraphic element) or a scratch protection film. Overlay layers formed in this way protect a security feature arranged underneath and / or give the document the required abrasion resistance.

Insofar as the term “pattern” is mentioned in the description and in the claims of the present application, this is to be understood as a somehow designed distribution of visible and / or elements that convey a tactile impression on one or more surfaces. These elements preferably result in a self-contained representation, for example a line, a group of lines, a line pattern, a picture element, or an alphanumeric character, a symbol, a coat of arms, a line, a formula or the like.

When designing the valuable or security product with a group of straight lines forming the tactile security feature to secure the portrait image, there is the possibility that the straight lines can extend from portrait edge to portrait edge, but also beyond. The mutual distance or the predefined positions of the intersection points of the straight lines can represent a further security feature which increases the security against forgery of the valuable or security product.

Furthermore, counterfeiting can be prevented by means of a predetermined position of the lines on the portrait or a predetermined position of the lines with respect to the portrait edge. In this context it is therefore possible for at least two of the lines to run parallel to one another at an angle of 15 degrees to 75 degrees with respect to a portrait image edge. An inclination of 45 degrees with respect to the portrait edge is preferred.

It is an advantage if the lines form a grid of lines. This line grid is formed from a plurality of straight lines that cross each other. The position of the points of intersection or the points of intersection in relation to at least one of the portrait edges can also be predetermined. It is also possible for the line grid to be formed with lines aligned at an incline with respect to a portrait image edge. Here, the line grid can also be aligned from 15 degrees to 75 degrees with respect to the portrait edge. It is preferably oriented at an angle of 45 degrees with respect to the portrait edges.

It has proven to be advantageous if the energy input of the laser into the at least one printing layer is dimensioned in such a way that color pigments of the at least one printing layer are evaporated or removed locally, in particular free of smoke. The valuable or security product is formed with at least one, preferably with several cavities in the printing layer, if the energy input by the laser is higher.

_{A CO 2} laser, for example, can be used as the laser, and excimer lasers and fiber lasers can also be used. These lasers are characterized by their positive property that they can be operated in a very wide range of possible powers, so that a desired energy input into the irradiated material can therefore be specified or freely selected. With a pulsed mode of the laser, high but brief bursts of energy can be introduced into the material, so that it is removed without burning and thus leaving traces of smoke.

In this context, it is therefore alternatively or additionally possible that an energy input from the laser into the at least one protective layer covering the printing layer is dimensioned in such a way that the protective layer is locally evaporated or removed, in particular free of smoke. In such a case, the valuable or security product is formed with at least one, preferably with several cavities in the protective layer.

The evaporation or ablation creates cavities. The cavities can be formed by holes, depressions, cavities, channels, pores, recesses, cavities and the like. The cavities in particular have a size in the micrometer range, ie the clear width / the thickness of the cavities is in the range from 10 μm to 500 μm, preferably in the range from 100 μm to 300 µm to 500 µm.

1. A) providing a carrier material,
2. B) Applying one or more print layers ( 140a ) and formation of a portrait image ( 110 ),
3. C) Developing a security feature ( 500 ) in at least one of the print layers ( 140a ) of the portrait image ( 110 ) by means of a laser, and / or
4. D) Developing a security feature ( 500 ) in at least one of the print layers ( 140a ) of the portrait image ( 110 ) covering protective layer ( 150 ) by means of the laser.

The advantages mentioned in connection with the valuable or security product also apply to the method according to the invention.

It is advantageous if the energy input of the laser is dimensioned in such a way that, during step C), color pigments of the at least one printing layer are evaporated or removed locally, in particular free of smoke.

As an alternative or in addition, it makes sense if the energy input of the laser is measured in such a way that during step D) the protective layer is evaporated or removed locally, in particular free of smoke.

Additionally or alternatively, the method is characterized in that the energy input of the laser is measured in such a way that the at least one printing layer is foamed locally during step C).

In an advantageous further development, the method is characterized in that the energy input of the laser is measured in such a way that the at least one protective layer covering the printing layer is foamed locally during step D). The lasered structures become more clearly visible as lines or surfaces appearing white due to the multitude of reflections of light refractions in the individual bubbles.

In 1 is one with a security feature 500 provided value or security product 100 shown. The value or security document 100 can be a personal document such as a passport, an identity card, an access card or the like, a check card or a bank note or another document. All of the following examples are described using such a card as representative of other document types.

In the 1 and 2 is the product of value or security 100 shown in the form of an identity card, for example as a laminate of several internal polymer layers 140 has been put together. For example, the polymer layers can consist of PC and / or PET. The individual layers can be unfilled or filled with fillers. In the latter case they are opaque, otherwise transparent. The layers can preferably be connected to one another in such a way that they form a monolithic block which practically cannot be split.

In 2 the individual layers before lamination are only shown for the sake of illustration. The interfaces are no longer visible in the finished laminate. The outer layers 150 the card can be formed as a final plastic protective film or consist of a protective varnish, which after lamination to the Card has been applied. The plastic protective film or the protective varnish is transparent so that the information underneath is visible from the outside. In particular, however, one or more printed layers remain 140a e.g. a portrait picture 110 visible, preferably immediately next to or behind the outer layer 150 is or are arranged.

The product of value or security 100 has a top 101 and a bottom 102 on. On the top 101 is the face or portrait image 110 of the holder of the card and data fields, namely, for example, a first data field 120 and a second data field 130 with card and holder data in plain text. D. The data in the first and second data fields 120 , 130 are made by printing layers that are on an outer layer of the document, but immediately below the outer protective layer 150 , lie.

It can be seen that the portrait image 110 a security feature to secure it 500 is assigned, which in the present case forms a pattern in the form of a grid of lines comprising a cluster of straight lines. The lines of the line grid run with respect to the portrait image edges of the portrait image 110 inclined at an angle of 45 degrees. Other angles of inclination for the straight lines of the grid are possible. It can be seen that the straight lines also extend over the portrait image edges of the portrait image 110 extend out and form protrusions with preferably a predetermined length. The length of these overhangs can be a function of further parameters, for example parameters or data from the data fields 120 , 130 must be set.

This security feature 500 is in a first variant in at least one of the printing layers 140a of the portrait image 110 applied or introduced by means of a laser. It can be used before laminating the in 2 shown composite are attached, or, with suitable focusing of the laser, only afterwards. As an alternative or in addition, in a further variant, there is the possibility that the security feature 500 into which the print layers 140a covering protective layer 150 is introduced.

In 3a is the security feature created by the laser 500 only in the print layer 140a educated. For this purpose, the power of the laser was measured in such a way that a targeted removal of the material of the printing layer 140a and a suitable cavity 502 , for example in the form of a line mentioned at the beginning or several such cavities in the form of a pattern, in particular in the form of a grid.

In 3b is the security feature created by the laser 500 only on the print layer 140a formed, in particular foamed, which is a raised area 504 arises. This is the material of the printing layer 140a preferably formed from a thermoplastic.

In 3b is the security feature created by the laser 500 only in the protective layer 150 educated. For this purpose, the power of the laser was measured in such a way that a targeted removal of the material of the protective layer 150 and a suitable cavity 502 , for example in the form of a line mentioned at the beginning or several such cavities in the form of a pattern, in particular in the form of a grid.

In 3b is the security feature created by the laser 500 only on the protective layer 150 formed, in particular foamed, which is a raised area 504 arises. This is the material of the protective layer 150 preferably also formed from a thermoplastic. When foaming, small bubbles form on the surface of the plastics, in which the light is reflected many times, making them appear white. In this way, patterns that look white on a transparent plastic, in particular lines or grids, can be generated.

In the case of a fine, but clearly visible, parallel grid of lines, in or above the portrait, even the inexperienced viewer will notice even small irregularities, be it in the form of changes in the ceiling of the line, the straight and unbroken course and the same lengths. This is a so-called "Level 1" feature.

In 3e is the security feature created by the laser 500 shown which one out in the print layer 140a and in the protective layer 150 existing cavities 502 and / or raised areas 504 is formed.

In 3f is another security feature 500 shown which one out in the print layer 140a and in the protective layer 150 existing cavities 502 and / or raised areas 504 is formed.
